To a-ZZ 'whom 'it may concern.'

Be it known that I, LELANDE. LENTZ, a

. citizen of the United States, residing at pairing Roads, of which' the following is a specification. s c

The object of thisinvention 1s toy provide a simple mechanism which may be secured to the rear deliveryend of a truck and oper-l atedby the travel of the truck to spread material for the purpose 'of resurfacing or repairing macadam roads! The invention also seeks to provide vnovel means for depositing the material and novel means for maintaining the material in condition to be `4 deposited and lincludes means whereby the quantity of material deposited may be easily regulated. Other objects of `the invention will appear in the course of the following description. In the accompanying drawings:

' -Fig. 5 -is a detail perspective viewof a for actuating the agitatorpart of the means or stirrera` f The truck may be of any preferred or `known type including a frame 1 and a dumping body 2 mountedupon the frame. In carrying out my invention, I secure to one of the rear wheels 3 of the truck a series of pins or tappets 4 which are arranged concentrically about. the axle of the wheels and maybesecured thereto 1n"any conven- Jient or preferred manner, the present illustration disclosing a circular plate 5 which is secured :ri idly tothe side of the vwheel, and carries t e pins or tappets adjacent its circular edge. I .also securev to the rear end of the body 2 a hopper which includesside plates 6, vthe main portions of said plates` i* of these side plates are extended in the plates. 'There is also a check plate 11 se-` cured to and extending between the upper rear corner portions of the wings 7j and terminating short of the bottom extension 9 whereby an opening is provided through which the material may pass from the body 2 into the hopper. An end gate l2 is' slidably mounted at its ends between the check plate 11 and cleats.13 secured to the wings 7 adjacent but in advance of the check plate, and this end gate has secured thereto the lower ends of cables or other flexible suspending devices 14 which extend upwardly and are secured to and wound upon a windlass or winding rod 15 which is mounted in suitable bearings upon the wings the adjacent wing 7 or the bearing for the winding rod to engage the ratchet so as to prevent reverse movement thereof and hold the end gate in any position to which it may be adjusted. I am thus-enabled to readily regulate the quantityv of material passing into the hopper so that waste of the material and choking of the hopper will be avoided.

The bottom and rear walls of the ho per' converge downwardly so as to provi e a restricted discharge passage, as shown at 19, and within the hopper partitions 20 are provided, the said partitionsl diverging downwardly and rearwardly so that thematerial will be spread effectually as it flows throughl they hopper and will be delivered evenly through the entire extent of the discharge passage. Mounted in any convenient manner upon the .rear side of the hopper so 4asto slide thereon is a cutoff 21 which may be set so as .to uncover the discharge 'opening to a greater or less extent and thereby regulate the flow of material to the dis'-` tributing pan 22. This cutoff plate 21 may be supported by links or other suspending devices 23 extending from the cutoff to a crank shaft 24 which is mounted in suit able bearings upon the rear side of the hopper and is equipped at one end with a crank or other form of handle 25. Set bolts 26 are mounted in the guides for the cutoff and are adapted to bind against the latter so as to hold it in a set position.

Extending across the lower end of the hopper and mounted in suitable bearings 27 on the under side thereof is a rod or shaft 28 by which the distributing pan 22 is pivotally mounted. This pan may conveniently consist of a metal plate having its end edges upturned to provide retaining flanges 29 and having its rear edge turned downwardly to provide a lip 30 over which the materlal may flow to be deposited upon the surface of the road. The pan is supported in its lowest position by chains or similar elements 31 secured at their opposite ends respectively to the outer rear corners of the pan and to the hopper at any convenient points of the same. At one end ofthe distributing pan is provided a forwardly extending arm or bracket 32,'the forward end of which is forked or bifurcated, as shown at 33, and within the fork or bifurcation I pivotally mount a lever 34 which has its front arm extending forwardly from the bracketbr arm 32 and has its rear arm projecting under the said bracket, as shown at 35. It is to be Vunderstood that the rear end of the arm 32 is rigid with the pan so as to oscillate or rock with it about theirod or shaft 28, and it is immaterial whether the arm and the bearings for the pan turn loosely on the rod or are secured to it to turn therewith, the rod in the one case being fixed on the hopper and in Athe other case being journaled thereon. A link v36 is pivotally connected at its lower end with the lever in common with the pivotal connection between the lever and the arm 32, as shown in Fig. 4, and has its upper end pivoted to the forward end of a crank or rocking arm 37 which is' fitted loosely on the end of an agitator shaft 38 which extends across the lower portion of the hopper at or immediately above the discharge passage 19 of the same. This agitator may be of any convenient form and is illustrated as consisting of a circular bar or rod provided with teeth or pins 39 throughout its surface. The rocking arm 37 is provided with a branch or offset 40 on which is pivotally hung a pawl 41 adapted to engage a ratchet disk 42 fixed concentrically uponvthe shaft 38.

The operation of the apparatus will, it is thought, be readily understood. The truck is loaded in the usual manner and, with the body in the normal horizontal position shown in 1, the hopper and the distributing pan 22 will be so dlsposed that the lever 34 will be rearwardlybeyond and out of the path of the tappets 4. When the `truck has been driven to the point where the material is to be spread, the truck body is tilted, as shown in Fig. 3, to a sufficient extent to dispose the forward extremity of the lever 34 between two of the tappets 4 so that, as the truck is then backed to and over the worn surface, the rotation of the rear wheels and of the tappets will cause the tappets to successively impinge upon the top of the lever at the forward end thereof and consequently vibrate the lever. The vibration of the lever will be transmitted through the link 36, the arm 37, pawl 41 and ratchet 42 to the agitator so that it will be caused to rotate or rock step by step and thereby agitate the material flowing through the hopper so that it will be prevented from accumulating to choke the discharge passage of the hopper. The agitator shaft will remain at rest as the front end of 'the lever 34 rises but will be actuated on the reverse movement so that the material will be fed tothe pan as the pan rises, the feed being retarded if not entirely cut off as the pan descends. V'Vhen the backing of the truck causes a tappet to impinge upon the lever 34, the front end sof the lever is obviously carried downwardly and, its rear end being in contact with the arm 32, the arm 32 will also swing ,downwardly about the center of the rod 28 and the pan will consequentl f be swung upwardly. When the tappet c ears the lever, the pan will descend under its weightI and the weight of the material therein to the extent permitted by the chains 31, the movement o the pan causing the niaterial to escape over the lip 2O in a relatively thin stream. The downward movement of the pan obviously imparts return movement to the arm 32 and the lever 34 and brings the lever into position to' be again actuated by the tappets 4. lVhen the truck is being driven to the scene of operations, the distributing pan will be in a horizontal position, as shown in Fig. 1, so that the material `cannot escape over the same except to the negligible extent which may llO be due to the vibration of the vehicle in traveling over the road, and this slight flow of the material may be prevented by lowering the cut-ofi' plate 21 until its lower edge lengages the surface 1'of the pan, whereupon the material will be held in the hopper. Excessive iow to the hopper may also `be cutofi' by adjusting the end gate 12 in an obntbaeoa 'construction and the arrangement of its parts so that itmay be readily secured to any truck and is not apt to get out of order,

while it will operate efficiently without rei quirlng any great attention `upon'the part of the workers. The lever 34 which actuates theagi-tator is brought into or out of operative position by. merely tilting the truck body tofdumping position and, as this lever andthe coo erating parts are arranged in l advance of t e point of discharge, it is not apt to be clogged by dust or particles of stonexa-nd will be in operative condition at alltirnes. The weight of the forward arm of the lever overbalances the rear arml thereof so that, when lthe truck body isgtilted, the

lever will assume operative relation to the actuating tappets and will retain that rela tion notwithstanding its vibration as a re-- sult of its engagement by the tappets. Shouldt the lever 34 from any cause be v swung forwardly into the path of the tappets while the truck is being' driven for.

ward, the tappets will impinge` against vthe under side ofthe lever and the lever will then merely rock about itspivotal connec- `tion with the arm 32 without imparting motion to thev arm.

Having thus described the is claimed as newiis;
